Unit circle is the source for the generation of the trigonometric function graphs. The quadrants from the unit circle, when placed horizontally in numerical order, create the basis for the trigonometric graphs. Hence This process of creating graphs from the unit circle is often called “unwrapping” the unit circle. Unit circle with Trigo Graph

Algebraic Expansion
The Expansions of Algebraic Expression The formula: a(b+c) = ab + ac Algebraic Expansion. (a+b)(c+d)=ac+ad+bc+bd and (a+b)(a-b)= a ² – b² difference of square (a+b)² = a² + 2ab + b² perfect square (a-b) ²=a²-2ab+b² Expansion
Binomial Theorem
This post is about binomial expansion of two terms expression. In this post questions are related with expansion of two terms. Find particular term and find coefficient of particular terms. The Binomial Theorem is a quick way of expanding a binomial expression that has been raised to some higher power. This topic in AS-level , […]
Co-ordinate geometry
A coordinate geometry is a branch of geometry. In this, the position of the points on the plane supported by an ordered pair of numbers also known as coordinates. Coordinate geometry deal about gradient , distance , mid point and equation of line. Also, condition of lines like parallel , perpendicular and inclined lines. In […]
